JAVA对DOM的一些解析、修改、新增操作

今天项目有需要对xml进行一些特定的操作，于是写了个小程序
 1 /*
 2 * param d: our project's color file
 3 * param s: the skin package's color file
 4 * result: the 'd' color will be replaced
 5 */
 6 public void changeColor(String d, String s)
 7 {

 9    //String d = "E:/workspace35/Lianluosms/color.xml";
10    //String s = "E:/workspace35/QiQiuMa/color.xml";

17  　　  Element root_default = doc_default.getDocumentElement();
18　　    NodeList nl_default = root_default.getElementsByTagName("color");
19 　　   Document doc_skin = db.parse(s);
20  　　  Element root_skin = doc_skin.getDocumentElement();

25           map_same.put(ed.getAttribute("name"), ed.getFirstChild().getNodeValue());
